Round 1 results up. I thought that was a tough set. I'm a bit annoyed to have wasted a bit of time convincing myself that the "Sum Next to 9" was impossible, and still haven't worked out what is going on with the magic square.

But otherwise a good run for me, even accounting for a silly mistake entering a code from puzzle 1 into puzzle 2's space (although in all honesty given my week so far I'm surprised my mistakes were limited to just that).

I presume there's a good reason David M isn't competing this year. Top 3 UK are remarkably close together:

Tiit smashed the set in 62 minutes, 10 minutes ahead of Kota in 2nd place, who was another 5 ahead of Tantan in 3rd. Results like that seem to confirm that this was pretty tough going in comparison to previous years. There were 19 finishers in total.
